rihis invention relates to connecters for sectional woveny wire belting and the like and of the character wherein the sections are alternately constructed from right and left-hand coiled strands of woven wire to prevent creepingof the belt laterally when passing over curved surfaces such as conveyor pulleys or drums and said right und left-hand coiled strands vwhen passing over lo said surfaces develop within the fabric or belt internal strains due to the sections of the right-hand coiled strands creeping latl erally in one direction while the sections of the left-hand coiled strands creep laterally in the opposite direction, causing the various strains to localize where the sections are connected to ether; and the present invention has for t e primary object, thepr0- vision of means for connecting the sections so together and capable of withstanding the strains and thereby preventing the belt or fabric from separating or tearing where the sections are connected.

Another object of this invention is the- 253 provision of a connecter provided' with relatively spaced closed loops or eyes, each of which is adapted to receive or have assed therethrough a convolution of the en right and left-hand coiled' strands of adjacent secse tions so that said sections are prevented from shifting laterally of each other and the coils or convolutions of the strands of adjacent sections are retained in alinement and not With these and other objects in view, this invention consists in certain novel features of construction, combination and arranffement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in t which j j Figure l is a fragmentary plan view illustrating the sections of a woven belt or fab-V ric of right and left-hand coiled strands of wire and the sections securedtogether by a y connecter constructed in accordance with my invention,

Figure 2 is a, similar view illustrating a modified form of my invention,

Figure 3 is a plan view of the connecter' prior to being twisted or braided, and

igure 4 is a similar view showing the connecter completed. Y Referring in detail to the drawing, the reference character l indicates a connecter for securing together sections 2 and 3 of a woven wire conveyor belt or fabric, wherein the section 2 is formed by woven left-hand coiled strands 4; and the section 3 of woven right-hand coiled strands 5 and as the end right and left-hand coiled strands of the sections cannot be woven together, the connecter l is employed for joining said sections.

The ends of the strands are looped together to provide a selvage 6 at each side edge yof the belt or fabric. The sections thus formed prevent the belt or fabric from creeping laterally of a curved surface, and due to the construction internal strains are developed within the belt or fabric caused by the sections of the right-hand coiled strands having a tendency to creep laterally in one direction and ,the sections of the left-hand coiled strands to creep laterally in an opposite direction, and the internalrstrains are delivered necter now in use. 'lhe conventional type oi connecter also permits the sections to shift laterally oi each other and with the internal i. strains actin with the lateral shifting of the sections ren er the conventional type of connecter uniit for further use in a comparatively short length of time, also the conventional type of connecterfjoins the sections so that the coiled strands of one section will be stag-` y gered or odset tothe coiled strands ot the adgacent section which places uneven strains on the connecter; and to overcome the abovenamed disadvantages, my connecter l is proy vided and consists ot a single strand ot vWire liti 'Z' bent upon itself to rovide parallel portions 8 connected by. a ight portion 9. rlhe side portions 8 are tivisted or. braided as shown in Figure 4: to provide spaced. closed loops or eyes `l0, each having a convolution -or coil oi' the strands i and 5 of the sections Zand 3 confined therein, thus holding them in alinement and preventing the sections from shitting laterally relative to each other.

`"llhe ends of the wires 7 are then welded together or otherwise secured, providing a con-y necter capable ot withstanding severe strains and one which vvill `prevent separation ot the sections and'vvill permit Hering between said sections.

By referring to Figure l ot' the drawing, it`

Will be noted that the ends oi the Vconnecter are positioned inwardly of the seivages of the belt'or" tabricand `therefore are protected from ivear,i"whilejin Figure 2 theconnecter passes through the looped ends ot the strands which iorm the selvages and in either torni oi" my invention the necessity oi securing the ends of the connecter to the edges ot the belt or fabric is obviated and as the ends of the conventional type of connecter are connected to the ends ot certain strands of the sections,

. they soon Wear or tear, allowing separation or parts may be made `Without departing troni i the spirit and scope ot my invention as claimed.
